LOS ANGELES—The Priority Product document on spray polyurethane foam systems issued by the California Department of Toxic Substances Control is riddled with inaccuracies and misinformation, according to the Adhesive and Sealant Council.
At a June 4 DTSC meeting in Los Angeles, ASC representatives urged the agency to remove the document from its website until it made all necessary corrections. This meeting was the third and last allowing public discussion of the agency's Priority Product regulation plans before rulemaking procedures begin this fall, the ASC said.
“Following the two earlier workshops, DTSC officials acknowledged misstatements in the Priority Product profile for spray polyurethane foam, yet they have failed to remove it from the Department website or make any changes to the document,” said Mark Collatz, ASC director of regulatory affairs.
Some of the errors in the document are egregiously basic, according to Collatz. For example, it states that toluene diisocyanate or hexamethylene diisocyanate may be minor components or residual constituents in spray polyurethane foam. This never happens, he said.
“This type of blatant misstatement not only hurts the manufacturers of those products, but also brings into question how the DTSC is getting their information,” Collatz said.
The ASC recommended that the agency develop an external advisory committee, made up of experts in the products under review, to avoid future errors.
